3.12 DHCP Lease Query
DHCP Lease Query allows ISAM to learn backs its DHCP IPv4 bindings, IPv6
bindings, and IPV6 PD routes, from the configured DHCP servers using lease query
after power on reset.
Figure 7 DHCP Lease Query
IHUB involves transactions in this lease query only when L3 DHCP relay is enabled,
and supports DHCPv4 single lease query based on IP address, and DHCPv4 and
DHCPv6 bulk lease query based on remote ID. Lease query based on other options
is not supported. IHUB involves transactions in this lease query only in base router
(IES) context, and maintains a maximum of 95 lease query sessions. That is to say,
